TVS diodes, also called Transient Voltage Suppression Diodes, are sets of diodes used to protect sensitive electronic components against large voltage surges. The 5KP190A-TP is a bidirectional device in an SMB package and features high surge current rating and 5.0kV peak pulse power capability. It provides reliable protection of up to 200V in the most adverse conditions.

The 5KP190A-TP package includes two LEDs that indicate the state of the TVS diode: when the diode is in a low-voltage state, the green LED is illuminated; when in action, i.e. in a high voltage state, the red LED is illuminated. This feature is important in applications where it is essential to monitor the state of the device.

In applications where noise sensitivity is important, the 5KP190A-TP design features low capacitance and a fast response time. This makes it suitable for use in data lines and can be used to protect active components from lightning and ESD strikes.

The 5KP190A- TP device’s general working principle is based on avalanche breakdown. This occurs when the voltage applied to the diode exceeds the avalanche voltage. The avalanche voltage is the breakdown voltage of the diode, and when it is exceeded, current travels through the diode’s junction and is released quickly. This process is instantaneous and is referred to as the "avalanche effect" or "avalanche sparkover".

During avalanche breakdown, the 5KP190A-TP device redirects the surge current away from sensitive components, protecting them from damage. Additionally, the device is also able to absorb and dissipate energy released during the breakdown. This ensures that the components stay safe in the event of a voltage surge.

The 5KP190A- TP device is commonly used in a variety of applications including automotive, industrial, telecom, consumer electronics, computing, and medical. It is also compliant with various standards including IEC 61000-4-2, IEC 61000-4-9, IEC 61000-4-5, and IEC 61000-4-14.

The 5KP190A-TP is a bidirectional device designed to protect sensitive electronic components against large voltage surges. It is based on the avalanche breakdown effect which redirects surge current away from vulnerable components. The device features a fast response time and low capacitance, making it suitable for use in data lines, as well as compliant with various industry standards. The 5KP190A-TP is a versatile device capable of being used in a variety of applications.
